Megan Fox and Brian Austin Green posed for this picture, which proves that the actress is very much pregnant!

After months of speculation, the actress finally revealed the truth via a snap that she posed for, with her husband Brian Austin Green in Hawaii this week.

She looked pregnant for the first time, since the rumours kicked off in March.

Since then, the media speculated whether the 25-year-old is pregnant and decided that she isn't – with her stomach remaining enviably flat throughout her first trimester.

But during this vacation, Megan stripped into a bikini and maxi skirt to reveal her neat bump as she posed with Brian.

To make doubly sure that everyone realised the couple were expecting their first baby together, Megan's hubby did the classic expecting father pose, smooching the baby's temporary home in a loving manner.

Megan and Brian have been married for almost two years, with Megan already a step mom to Brian's nine-year-old son Kassius.

Speaking about his wife's parenting skills recently, Brian said that Megan is a natural with Kassius. He said: "She's an amazing stepmom. My son loves her. They have a great relationship. She's always had a special bond with him."

When talking about having kids of her own in the past, Megan always said she was waiting for the right time.

She told a magazine in February: "I've always really loved kids. I was a good babysitter. I've always loved babies. I relate to kids pretty well. It will happen when it's meant to happen."
